Jagadish Chandra Bose (1858-1937)
- He was a physicist-turned-biologist who had shown, more than a century ago, that plants experienced sensations and were able to feel pleasure and pain just like animals.
- He invented the crescograph, a device for measuring the growth of plants.
- Jagadish Chandra Bose is remembered for two things — his work on wireless transmission of signals, and on the physiology of plants.
- He is also credited as one of the first contributors to solid state physics.
- He had anticipated the p-type and n-type semiconductors.
- Bose is widely believed to be the first one to generate electromagnetic signals in the microwave range.
- He was the first one to come up with radio receivers, which enabled wireless telegraphy.
His study of plants
- The simple experiments of Bose revealed a high degree of similarity in the responses of plant and animal tissues to external stimuli. This principle was amply demonstrated later by biophysicists, using highly sophisticated instruments.
Controversy
- Bose regarded plants to be the “intermediates in a continuum that extended between animals and the non-living materials”.
Ethical view
- He was being approached by a big businessman in Europe with the offer to get his work patented. Bose not just rejected the offer, he felt disgusted at the idea of making money from science.
